So I deleted lines 204 and 207 (#ifdef HAVE_LIBLEPT , #endif ) from viewer/scrollview.h than compilation continued up to this error: g++ -DHAVE_CONFIG_H -I. -I.. -I../ccutil -I../ccstruct -I../image -I../viewer -I../ccops -I../dict -I../classify -I../ccmain -I../wordrec -I../cutil -I../textord -I/usr/local/include/liblept -g -O2 -MT tesseractmain.o -MD -MP -MF .deps/tesseractmain.Tpo -c -o tesseractmain.o tesseractmain.cpp tesseractmain.cpp: In function ‘int main(int, char**)’: tesseractmain.cpp:227: error: ‘pix’ was not declared in this scope So I put declaration to line 225 in api/tesseractmain.cpp: PIX *pix; Than compilation continue but soon it fails on with this message: g++ -g -O2 -o tesseract tesseractmain.o libtesseract_api.a -llept -ltiff -lpthread -ljpeg -lpng -lz -lm libtesseract_api.a(libtesseract_api.o): In function `sv_show_sub_image(IMAGE*, int, int, int, int, ScrollView*, int, int)': /usr/src/tesseract-ocr-r354/image/svshowim.cpp:37: undefined reference to `ScrollView::Image(Pix*, int, int)' collect2: ld returned 1 exit status make[3]: *** [tesseract] Error 1 I am not able to solve this. It looks to me like problem with leptonlib (I have leptonlib-1.65) - all problems where between #ifdef HAVE_LIBLEPT , #endif. But I was able to build r326 without problem with leptonlib-1.65. Zd.
